Hi, there are two warnings given on the mPower for low battery. One is based on a chip that keeps track of how much power it thinks has gone into and out of the battery, and this will be affected (although not greatly) by it not being calibrated. The other warning is given when the battery voltage hits a certain level, and will not be affected by calibration. Especially if it's a unit on loan to you, I wouldn't worry about whether it's calibrated or not - although repeated failure to calibrate can indicate a battery problem.
If you want to know the percentage of battery power the unit thinks it still has, you can go into support information mode and press P, and it will tell you even if it doesn't think it's accurate. regards, Andy. ---- Andrew Riden Software Development Engineer HumanWare Ltd. 11 Mary Muller Drive, Christchurch, New Zealand.
